It is probably chemically dried then. Still food grade though, intended for tinctures.
I likes me some nerdy stuff, glad to know that. That would be why the 'organic' tincture alcohol tops out at 190 proof.
So if you got an extract made from 100% ABV alcohol, then allowed the alcohol to evaporate, you might find up to 4.4% water left behind as if by magic?
Have an interesting fact back
The reason alcohol is measure in '% proof' is because sailors on board navy ships were concerned that their tot of rum was watered down. To show it had not been, the bosun would pour some on gunpowder and if it could still be lit, that was 'proof' that the rum was not watered down.
And yes, that was around the 50% ABV mark.
